PAPER-RULING-PEN UNDERLIFT.

Specification of Letters Patent.

Patented July 5,1921.

Application filed. September 13, 1920. Serial No. 409,828.

To all w ham it may concern Be it known that I, CAMILLE J. LA VIeunUR, a subject of the King of Great Britain, and resident of Beachmont, county of Suffolk, State of Massachusetts, have invented an Improvement in Paper-Ruling- Pen Underlifts, of which the following description, in connection with the accompanying drawing, is a specification, like char acters on the drawing representing like parts.

This invention relates to improvements in pen-lifting mechanisms for paper ruling machines of the type in which a web of paper, or a series of sheets of paper, are cast continuously beneath a series of ruling pens, means being provided to enable the pens to be lifted, if desired, at predetermined intervals. Such machines are adapted for use in plain or continuous ruling or when used with pen-lifting mechanisms to leave unruled spaces for headings, etc.

The object of the present invention is to provide an improved under-lifting mechanism, supplemental to the mechanism for lifting the series of pens, which may operate upon one or more pens to lift'the' same from the paper without effecting the operation of the remaining pens of the series, thereby enabling the machine to make rulings for sub-heads, etc.

In such supplemental pen-lifting mechanisms which have heretofore been constructed the pen-lifting instrumentality has usually been in the form of an arm, or a series of arms, which are positioned along a rock shaft to underlie the selected pens which are to be lifted independently of the others, the pen-lifting arms being secured to the rock shaft by a clamp which extends longitudinally of the shaft and is connected thereto by screws.

In other instances a split rock shaft is provided and the pen-lifting instrumentalities clamped between sections of it. In such instances it is necessary to release the clamping member in order to remove one of the under-lifting arms or to adjust them to. different positions. The object of the present invention is to provide an under-lifting device for pens which may be quickly attached to an actuating rocker and which, preferably, may be adjusted at any position along the rocker without efiecting any other underlifting instrumentality. which may be carried by the rocker.

A further object of the invention is to provide a pen under-lifting instrumentallty which may be more quickly assembled upon a machine and removed therefrom than devices which have heretofore been produced.

Other objects and features of the invention will more fully appear from the following description and the accompanying drawings and will be pointed out in the annexed claims.

The drawings illustrate a pen-lifting instrumentality as applied to a usual form of paper ruling machine and inasmuch as the general construction of the machine is well known only such mechanisms as relate to the invention herein are illustrated in the drawing.

In the drawings:

Figure 1 is a side elevation, partly in section, of a portion of a ruling machine showing the pen beam holding a series of pens in operative relation to a web of paper and illustrating the application of the underlifting mechanism for the pen applied thereto, a Fig. 2 is a plan view of the mechanism illustrated in Fig. 1, and,

. Fig. 3 is a perspective view of a preferred form of under-lifting clip showing the manner in which it is clamped upon the rocker.

The under-lifting mechanism for the pens of ruling machines embodying my invention may be applied substantially to any usual type of ruling machines which are now in commercial use. In such machines, a portion of one of which is illustrated in the drawing, the paper 1 is carried upon a web 2 over a suitable support 3 beneath a series of ruling pens, the support 3, which is illustrated herein, being carried upon a shelf 4: suitably secured to the frame 5 of the machine.

Brackets or stands 6, rising from the frame 5, are provided with journals for the shaft 7 of a pen beam 8 which extends trans versely of the machine and is provided with a suitable pen clamp 9 in which a series of pens 10 are so supported that their ends rest upon the paper directly over the support 3.

When these pens are supplied with ink, and the paper drawn beneath them, parallel lines are ruled upon the paper at such distances apart as is determined by the position of the pens, which are adjustably $6- cured in the clamp 9.

In machines of this character means arev usually provided for rocking thepen beam 8 about the axis of its shaft 7 to remove all of the pens from engagement with the paper, as for example, when a blank space is desired between adjacent sheets cut from the web for the purpose of making headings.

It is frequently desirable to provide means for interrupting the continuous line formed by one or severalof the pens in order, for example, to provide asupplemental blank space for the entry of the sub-head upon the ruled sheet.

I The present invention contemplates the provision of an under-lifting mechanism which may be quickly assembled or adjusted to enable one or several of the ruling pens to be raised at predetermined intervals with out interfering with the operation of the remaining pens carried by the pen beam. In order to performthis function a rocker 11 is provided which is journaled in bearings 12 in suitable brackets supported by the frame. The shaft of the rocker 11 may be of any form, but preferably is in the form of a cylindrical rock shaft provided with recesses by means of which the pen-lifting instrumentality may be fixedly secured to the shaft.

As illustrated herein the rocker 11 is provided withtwo diametrically, oppositely disposed grooves 13 and 14 which are engaged by a clamping member which preferably is an integral portion of an under-lifting clip.

In the preferred embodiment of the invention illustrated herein the clip is in the form of a thin fiat plate 15 formed-of tempered brass or steel, or other spring metal, preferably having a substantially straight portion to engage the underside of the pen and an arched portion 16 of such form as to embrace the rocker or shaft 11, one or both ends of the arched portion being so formed as to engage one or both of the recesses or grooves 13 and 14. In order to insure a proper clamping of the clip upon the rock shaft the arch-shaped portion 16 is of greater length than the circumferential distance betwee the grooves 13 and 14.

Preferably the arch-shaped member is somewhat flattened upon its top so that the flat portion 17 engagesthe top of the rocker 11. Theflattening of the upper portion of the arch causes the sect-ions of the arch adj acent the flat portions to bulge away from the cylindrical surface of the rocker leaving spaces 18 and 19 therebetween. By reason of this flattened construction a better clamping action is afforded than if the archshaped member conformed closely to the contour of the cylinder.

; The outer end 20of the arch-shaped portion desirably is curved to fit closely within the groove 14, while the junction 21 between the other end of the arch-shaped portion and Any suitable mechanism may be employed for actuating the rocker 11. As illustrated herein the rocker 11 is provided with an arm 22 which rests upon the surface of the usual cam head or striker which is driven in the usual manner. illustrated herein is a cylinder having two peripheral grooves 24 in which cam sections 25 are secured by clamping screws 26 seated in and extending through the walls of the grooves 24. Upon rotation ofthe cam head the cam 25 engages the arm 22 at predetermined intervals thereby rocking the shaft 11 and causing the pen lifter 15 to raise the particular pen, which it underlies, from contact with the paper. I 7

As illustrated herein usual means are-employed for simultaneously lifting all of the pens from the paper. This means comprises a lever 28 which at its lower end is provided with a shoe which rests upon thecam head or striker 23 and is adapted to be engaged by the cam 25 which is detachably secured in one of the grooves 24. The other end of the arm 28 is pivotally mounted upon a shaft 29 in a boss 30 extending upwardly from the bracket 6 which supports the pen beam.

Adjusting screws 31, 32, threaded through the arm 28 and bearing upon the pen beam 8 upon oppositesides of its pivotal support 7 serve to tilt the pen beam in such a manner as may be required for different lengths or shapes of pens. p

The arm 28 is also provided with a lateral extension 33 into which a set screw 34 is threaded, the lower end of said set screw resting upon a ledge or arm 35 projecting from the bracket 6'. By adjusting the set screw 34: the downward movement of the arm 28 may be so limited as to cause the pens to exert a desired downward pressure upon the paper. This construction is, however, usual and is not a part of the present invention which relates only to under-lifting mechanisms.

The cam head or striker as In the operation of the machine the paper I 1 is drawn beneath the pens 10 and the pen beam 8 actuated through a suitable mechanism to raise and lower the pens as is usual in the art. The cam head 23 is rotated through the usual mechanism and acts line thereby interrupted during such time as is determined by the length of the cam 25 which acts upon the arm 22.

If at any time it is desired to cause the pens thus selected to continue their lines the same as the other pens of the series the clips 15 may be slipped from beneath the pens longitudinally of the rocker without the necessity of removing the clips from the rocker, or the clips may be easily removed from the rocker by spreading the archshaped clamping portion sufliciently to detach the curved portions 20, 21 from engagement with the grooves 13 and 14:.

The clips 15 may, of course, be made of any desired width and form and may be employed to raise a single pen, or a series of adjacent pens, or may be so formed as to extend under and raise several pens.

It will be understood that the embodiment of the invention disclosed herein is illustrative and not restrictive and that various changes in construction, form, material and operation may be made within the spirit and scape of the following claims.
